VEHICLE-AXLE.

$PEGIFICATION forming part Of Letters Patent N0. 694,940, dated March 11, 1902.

Application filed July 18, 1901. Serial No. 6 8,73 7. (No model.)

erence being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to vehicle-axles which are non-rotary and have a journal extending into a wheel-hub. Said invention is speciallyapplicable to small cars forexample, mineca-rs. Such cars must. be strong and at the repair. It is the object of my invention to meet these requirements.

My improved axle is composed of only three principal pieces, two journals and a beam connecting said journals, and said journals are duplicates and are simple integral pieces adapted to be cast in an ordinary two-part mold in substantially complete form.

In the accompanying drawings, Figure 1 is a side elevation of one half of an axle embodying my improvement and applied to a wheel, the upper half of the latter being in As the other end of said axle is a duplicate of the end shown, it is deemed unnecessary to show the entire axle. Fig. 2 is a vertical section on line 2 2 of Fig. 1, looking toward the left. Fig. 3 is a plan of the journal shown in Fig. 1, a portion being in horizontal section on the line 3 3 and the beam being shown in dotted lines. Fig. 4 is an elevation of the inner end of said j ournal. Fig. 5 is a plan ofsaid journal. Fig. 6 is an elevation of the outer end of said journal.

Referring to said drawings, A is the journal. 0. is the beam. B is a stub, shank orstem extending endwise from said journal into said beam. A is an annular flange surrounding said journal adjacent to said stub or stem.

A is an oil-chamber located within the journal A. The outer end wall A has extending through it a vertical aperture A for receiving a cotter pin or linchpin D. Said end wall A is shown thickened vertically at either side of said aperture. The space between said flange A and said cotter-pin D is occupied by the wheel E and the washer F. Said wheel may be of any construction suitable for mine-cars or cars of similar type. It may have an ordinary hub E and a bushing E located within said "hub and secured, preferably, by being fitted so closely as to require the bottom of the journal (where the greater wear takes place) than at the top. An oil inlet A. (see Figs. 1, 6, and 4,) extends through the upper portion of the outer end wall. I This is for the insertion of lubricating-oil into said chamber. At the'bottom of said oil-chamber I place one or more outlets A", which allow the oil in said chamber to escape into the space between said journal and the interior of the bushing E If more than one such hole is used, they are-preferably placed in a line parallel to the axis of thejournal, so as to bring all said holes where they will be covered by the inner face of the hub when the car is at rest, to the end that oil may not escape from said chamber when the car is not running. When the car is in motion, the line of contact between said journal and hub is usually atone side of the line of said holes, and when that is not the case said holes are uncovered more or less by the oscillation of the wheel.

On top of said journal (see Figs. 5, 1, and 2) is a channel A parallel to the axis of the journal, and from the bottom of said channel one or more apertures A extend verti cally through the wall of said journal. The function of said channel and said apertures is to receive from the interior of said bushing any excessive oil and deliver it again into said oil-chamber. The stub or. stem 13 is formed integral with said journal and has a flat upper face, adapted to receive the hori zontal web of the channel-beam O. Said stub is preferably elevated with reference to the axis of said journal in order that the upper level face of said stub may extend quite to the flange A, while there is space below said face and adjacent to said flange for a bodyof metal of relatively large cross-section sufficient to afford the requisite degree of strength for a proper union between the beam and the journal. The main portion of said stub is just large enough to fill the interior of the channel-beam 0; but beneath such main portion is the oblique web B, extending from said main portion to the lower portion of the end wall of said journal and having extensions B reaching laterally beneath the depending vertical walls C of the channelbeam. Said stub is provided with vertical apertures B for receiving rivets or bolts C extending through said shank and said channel-beam. It will be observed that in holding said beam and stub together said rivets or bolts are assisted by the close fitting of said beam to the upper and lateral" faces of said stub and against the end of the wall of the journal adjacent to said flange A and upon the lateral extensions B As to this union, itis to be observed that I attain great economy through the adoption of the forms shown. By forming the journal and its stub-shank as shown it becomes possible to use ordinary commercial iron or steel channel beams, and these need only be cut at right angles to the proper length and drilled at two places at each end to receive the rivets G These are simple and inexpensive operations. The upper face of the beam must be flat in order to best receive the car-body.

Notwithstanding its peculiarities in form and consequent advantages the journal is simple and inexpensive in production. It is merely a one-piece casting made in an ordinary two-part mold dividing on a central vertical plane, machine-work being needed only for turning off the exterior of the journal to remove the part excessively hardened by chilling and to make the journal accurately fit the interior of-the bushing E Should it become necessary to replace a journal or a beam, these parts can readily be separated by cutting the heads of the rivets C Cheapness and compactness are important advantages in mine-cars and similar vehicles. In the tunnels and shafts of mines a car must be so constructed as to occupy the least possible space, and at the same time it must be adapted to carry the largest possibleload. By my construction the axle and the car-body are brought close to the rails and a large degree of strength is attained, and this is accomplished by such an inexpensive construction as the market demands.

I claim as my invention- 1. In a vehicle-axle, a one-piece cast stubjournal having an interior oil-chamber and having extending through its outer end wall a vertical aperture adapted to receive a cotter-pin, substantially as described.

2. In a vehicle-axle, a one-piece cast stubjournal having an interior oil-chamber and having an aperture extending from said chamher through the lower wall of said journal, and having at its upper portion an aperture leading into said chamber, substantially as described.

3. In a vehicle-axle, a one-piece cast stubjonrnal having an annular flange and having an interior oil-chamber, and having extending through its outer end wall a vertical aperture adapted to receive a cotter-pin, substantially as described.

l. In a vehicle-axle, a one-piece cast stubjournal having an interior oil-chamber and having extending through the upper portion of its outer end wall an oil-inlet, substantially as described.

5. In a vehicle-axle, a one-piece cast stubjournal having an annular flange and having an interior oil-chamber and having extending through the upper portion of its outer end wall an oil-inlet, substantially as described.

6. In a. vehicle-axle, a one-piece cast stubjournal having'an interior oil-chamber and having extending through its outer end wall a vertical aperture for the insertion of a cotter-pin and an aperture extending through said end wall into said chamber, to serve as as oil-inlet, substantially as described.

7. In a vehicle-axle, a one-piece cast stubjournal having a cylindric internal oil-chamber with its axis parallel to and above the axis of said journal, wherebythe lower portion of the Wall of said journal is made thicker than the upper portion of said wall, substantially as described.

8. In a vehicle-axle, a onepiece journal having an interior longitudinal oil-chamber, and having a flange, A, and'a shank or stem, 13, with a flat upper face and vertical apertures for receiving rivets, and a web extending from said shank downward to the lower portion of the inner end wall of said journal, substantially as described.

9. In a vehicle-axle, a one-piece journal having a longitudinal, interior oil-chamber, an aperture extending through the lower wall of said journal, and a channel and an aperture in the upper portion of said wall, substantially as described,

10. In a vehicle-axle, a journal having an internal oil-chamber, an aperture extending through the bottom wall of said chamber and a channel in the upper wall of said chamber and an aperture extending from said channel through said upper wall, substantially as described.

In testimony whereof I aflix my signature, in presence of two witnesses, this 3d day of July in the year 1901.
